Meats and Sweets Are Not Healthy Treats


Dietary factors, second only to tobacco as a preventable cause of cancer, account for about 30 percent of all cancers in Western countries and approximately 20 percent in developing countries. Announcing findings in 2005 of its twenty-year-long study tracking 150,000 Americans, the American Cancer Society found that men and women who ate the most amounts of red meat (compared with those who ate more poultry, fish, and non-meats) had a 53 percent higher risk of distal colon cancer.

Also in 2005, a study by Johns Hopkins Bloomberg School of Health, in which 1 million Koreans were tracked for ten years, reported that high sugar consumption could be a risk factor in developing several types of cancer. These researchers suggest that glucose intolerance may be one way that obesity increases cancer risk and that rising obesity rates may increase future cancer rates.

Potato Power


Purple-fleshed potatoes are a rich source of anthocyanins – potent plant-based antioxidant compounds.  Jairam K.P. Vanamala. from Penn State University (Pennsylvania, USA), and colleagues previously discovered that baked purple-fleshed potato and its extracts suppress early and advanced human colon cancer cell proliferation and induced apoptosis (cell death).  In the current study, the team conducted an initial laboratory study in which they observed that baked purple-fleshed potato extract suppressed the spread of colon cancer stem cells while increasing their deaths. The researchers the tested the effect of whole baked purple potatoes on mice with colon cancer and found similar results.  Explaining that as well as anthocyanins, purple potatoes, contain resistant starch, which serves as a food for the gut bacteria, that the bacteria can covert to beneficial short-chain fatty acids such as butyric acid – a substance that regulates immune function in the gut and suppresses chronic inflammation, the investigators point out that the portion size for human consumption equates to about the same as eating one baked, large purple-fleshed potato per day.
